Geneva LIVE: Koenigsegg Regera

The Swedish megacar boasts an extraordinary 1,500 horsepower and 1,475 lb-ft of torque, allowing the car to reach 249 mph in less than 20 seconds.

Koenigsegg has pulled the veil from the Regera, its new flagship 'megacar' that aims to take on the McLaren P1 and LaFerrari.

The Swedish automaker has taken a luxury approach with the Regera, stepping away from its traditional lightweight race-inspired road cars. Despite the comfortable accoutrements, the company claims it will be the fastest accelerating, most powerful production car ever built.

A unique hybrid system combines output a 5.0-liter turbocharged V8 engine and three electric motors, connected to a 9 kWh battery pack tucked in the carbon-Kevlar chassis tunnel. Notably, Christian von Koenigsegg's direct-drive invention eschews a traditional gearbox in favor of a direct connection between the internal-combustion engine and the rear axle. The engine fires up at speeds above 30 mph and reaches redline at top speed.

"During highway travel, for example, the KDD reduces drivetrain losses, compared to traditional transmission or CVT by over 50 percent, as there is no step up or step down gear working in series with the final drive -- just direct power transmission from the engine to the wheels," the company claims.

The direct-drive hybrid technology is said to add less than 200 lbs over a non-hybrid setup with a traditional seven-speed gearbox, resulting in a wet curb weight of 3,589 lb.

The Regera boasts an extraordinary combined output of over 1,500 horsepower and 1,475 lb-ft of torque. To put things into perspective, Koenigsegg promises the car can rocket from 93 mph to 155 mph in just 3.2 seconds. Getting to 249 mph from a dead stop allegedly takes 20 seconds -- more than 30 seconds quicker than a Bugatti Veyron.

Occupants are cushioned by memory foam seats with eight-way adjustments, rather than stiff racing seats. The engine and other powertrain components rest on active soft mounts, enabling the Regera to instantly switch from a plush, quiet ride to a stiffer sport mode during spirited driving. It can even be driven silently in all-electric mode for up to 22 miles.

Only 80 examples will be built, in part because the number "symbolizes the principle of domination, control and achievement in Pythagorean Numerology."
